A cavity-backed microstrip patch antenna array was optimized in the Ku band. The backing cavity was designed under each patch antenna of the array in order to increase the bandwidth and minimize the intercoupling among the radiating elements. Substrate integrated waveguide (SIW) technology was employed to fabricate the above-mentioned cavity below the radiating patch. More precisely, four microstrip array antennas, made by 2 × 2, 4 × 4, 8 × 8, and 16 × 16 elements were designed, fabricated, and characterized. The measured maximum gain was G = 13 dBi, G = 18.7 dBi, G = 23.8 dBi, and G = 29.2 dBi, respectively. The performance of the proposed antenna arrays was evaluated in terms of radiation pattern and bandwidth. An extensive feasibility investigation was performed even from the point of different materials/costs in order to state the potential of the engineered antennas in actual applications. The obtained results indicate that a cavity-backed microstrip patch antenna is a feasible solution for broadband digital radio and other satellite communication overall for niche applications.

This paper presents analysis and design of a dual circularly polarized 16×16 Ku band antenna array with emphasis on its feeding network. The proposed antenna is designed for on-move satellite communication system where the radiation pattern and the side-lobe level should meet the ITU standards to avoid interference with other satellite systems. This requirement is obtained by using non-uniform feeding distribution network. In addition, dual circular polarization operation requires sequential feeding networks with appropriate phase shift sequences. The proposed antenna is divided into 16 sub-cells of 4×4 radiating elements. The elements inside the sub-cell are fed by uniform dual sequential feeding networks. These sub-cells are connected together via two non-uniform feeding networks on a single layer in the shape of two interlaced fork configurations. In addition, cascaded power dividers are used to achieve the required low power division ratios between some of the sub-cells according to the required feeding distribution. These modifications simplify the fabrication process of the proposed antenna structure and reduce the required layers while satisfying the required radiation parameters.
